Paste computer clipboard to the device on Ctrl+v.
The other direction (pasting the device clipboard to the computer) is
not implemented. It would require a communication channel from the
device to the computer, other than the socket used by the video stream.
Characters like 'é' or 'î' are not resolved by getEvents(). For example,
getEvents("é") returns null.
However, it is possible to decompose them. For example,
getEvents("\u0301e") returns the events generating "é".
Thank you Philippe! ;)
In handleEvent(), connection.receiveControlEvent() may never return
null: either it returns a valid ControlEvent, either it throws an
Exception.
Therefore, there is no need to propagate a flag to indicate whether it
returned a valid ControlEvent.
The right-click is almost useless on Android, so use it to turn the
screen on.
Add a new control event type (command) to request the server to turn the
screen on.
